Strengths & Weaknesses

Sparkle

Strengths
  • Ultimate “The Hero with a Thousand Faces” Recovers 4 Skill Points for the team and grants all allies Cipher—time it for the carry’s damage window instead of casting on cooldown out of habit.
  • Skill “Dreamdiver” action-advances an ally with a damage amp attached—this is the spend that keeps the rotation honest.
  • Talent “Red Herring” While Sparkle is on the battlefield, additionally increases the max number of Skill Points by 2—miss the stack conditions and the burst window feels empty.
Weaknesses
  • Buff windows on “The Hero with a Thousand Faces” are short—casting them when the carry cannot attack wastes the CRIT DMG/ATK amp for a full cycle.
  • Sparkle’s Skill is often the expensive part of the rotation; SP-negative teams force Basic ATKs and you lose the advance/amp that made the unit worth playing.
  • Spamming “Dreamdiver” every turn without watching Skill Points strands the rest of the team—Sparkle is often the SP sink.

Sunday

Strengths
  • Ultimate “Ode to Caress and Cicatrix” refunds a meaningful chunk of Energy inside the Skill—time it for the carry’s damage window instead of casting on cooldown out of habit.
  • “Benison of Paper and Rites” action-advances an ally with a damage amp attached—one Skill Point buys a full extra carry turn.
  • Sunday’s memosprite/summon adds a second actor that hits and breaks without always spending the team’s Skill Points.
